Definitions

  • FIG. 1B is a cross-sectional view of a composited stationary shaft with double-sided-supporting according to a second embodiment
  • FIG. 6 is a cross-sectional view of a containment shell bearing a force and a moment according to a first embodiment
  • the magnetic drive pump comprises a pump casing 4 , a front support 43 , an impeller 5 , a containment shell 41 , an inner rotor 7 , an out rotor 92 , a stationary shaft 3 and a bracket 91 .
  • the stationary shaft 3 is a double-sided-supported structure made of ceramic material with anti-corrosion and wear resistance properties.
  • the front end of the stationary shaft 3 is supported by the front support 43 of the pump casing 4 and the rear end of the stationary shaft 3 is supported and fixed by the rear shaft seat 413 of the containment shell 41 .
  • a central portion of the stationary shaft 3 mates with a ceramic bearing 79 of the inner rotor 7 to rotate.
  • the length of the central portion satisfies with the length of the ceramic bearing 79 for bearing a combined force applied to the inner rotor 7 and an axial free-movement space of the inner rotor 7 is reserved.
  • the rib plate 431 and the front shaft seat 433 of the front support 43 provide a highly stiff supporting for the stationary shaft 3 as well as a hold length L so that the problem that the strength of the plastic is reduced when the temperature rises is solved.
  • a magnetic drive pump which includes a double-sided-supported composited stationary shaft is applied in high power and at high temperature, FIG. 1B .
  • the out rotor 92 is a ring cup-shaped structure comprising multiple outer permanent magnets 93 , an outer rotor yoke 92 b and a shaft adapter 92 a .
  • the shaft adapter 92 a and a drive motor shaft 95 are fixed to each other.
  • the multiple outer permanent magnets 93 are installed on an interior ring surface of the outer rotor yoke 92 b .
  • the drive motor shaft 95 drives the out rotor 92 to rotate.
  • the containment shell 41 is installed between the inner rotor 7 with inner permanent magnets 71 and outer rotor 92 with the outer permanent magnets 93 , the out rotor 92 is installed at the outside and correspondingly positioned to the inner rotor 7 , and both outer and inner magnets are arranged radially and oppositely, and are magnetically attracted to each other.
  • the outer permanent magnets 93 attract the inner permanent magnets 71 to drive the inner rotor 7 to rotate.
  • the cross-sectional area of the rib plate 431 and the cone body 432 plus the thickness of the resin enclosure 43 a is the blockage area of the cross-sectional area of the inlet channel.
  • the residual cross-sectional area of the inlet channel is the flowing area.
  • the flow velocity of the fluid is inversely and linearly proportional to the flow area, and the flow resistance is greatly proportional to the square of the flow velocity. In other words, the resistance is quadratic proportional to the reciprocal of increase of the effective flow area.
  • the two following embodiments describe the inner diameter of the pump inlet 44 which is not increased particularly.
  • FIG. 4A describes the front support 43 , an impeller 5 and a pump casing 4 in the first embodiment.
  • the impeller 5 is assembled in the pump casing 4 (please refer to FIG. 1A together).
  • a front support 43 may axially pass through the hub aperture 54 .
  • the inner rotor 7 is encapsulated with a resin enclosure 74 made of fluoropolymer.
  • the ceramic bearing 79 is installed in the central hole of the inner rotor 7 .
  • the hub plate 52 is used for being connected to the axially extended part 76 of the inner rotor 7 so that the impeller 5 and the inner rotor 7 are integrated into one piece or are combined into one piece together.
